Scope Mounts

A one-piece cantilever mount holds your riflescope as a single unit instead of two separate rings, with the rings carried forward on a built-in arm. That offset sets correct eye relief over a flat-top rail and keeps alignment consistent. Most fit standard Picatinny-style rails, so check your tube diameter first.

We carry Athlon's Armor, AR Tactical and Precision Pro mounts for 1-inch, 30mm and 34mm tubes, with 0 MOA and 20 MOA options. The 20 MOA versions add elevation for long-range dialing.

Which mount design

Cantilever

A cantilever mount carries the rings forward on an arm, which puts the scope's eyepiece over the charging handle for proper eye relief on an AR-15, AR-10 or other MSR, and as one piece it needs no ring alignment. The Armor mounts are low-profile and snag-free, the AR Tactical mounts are made in the USA with a scalloped profile, and the Precision Pro mounts use 4-screw ring caps on a 2-nut base with recoil lug cross-bolts.

Quick-detach

The Precision Pro QD mounts add quick-detach levers, so the scope comes off and goes back on without tools, to reach iron sights or swap optics, and they come in 30 mm and 34 mm with or without a 20 MOA cant.

Center

The Precision Pro Center mount sits the rings over the base for bolt-action and traditional rifles, with balanced weight and direct rail-to-scope alignment.

Tube size and cant

Match the ring size to your scope's tube exactly: 1 inch, 30 mm or 34 mm. A 20 MOA mount is angled to extend the elevation travel you can use for long range, and a 0 MOA mount has no cant.

Frequently Asked Questions

Do I need a 20 MOA mount?

Choose one if you dial for long range: the 20 MOA cant extends the elevation travel you can use.

Cantilever or center mount?

Cantilever for AR-pattern rifles, where the forward offset gives proper eye relief behind the charging handle. Center for bolt actions and traditional rifles.

Will it fit my rail?

The cantilever mounts fit Picatinny rails, and the Armor and AR Tactical mounts are made for AR-15, AR-10 and MSR platforms.

What are they made of?

Aircraft-grade aluminum, on every mount here.
